Just be warned I bought new and we don’t drive it wild or anything but both rear tires (non staggered 21”) were at 3mm tread after 10k miles and I had to replace them. Was shocking.
Regarding the X3M - I have about 9 months and 6k miles or so dailying mine. It is firm but I don't believe it's as punishing as most reviews mention. The thing is a monster man. I don't know why anyone would need anything more in a daily. It handles easily as good as my RS3 did and maybe even less body roll despite being much higher CoG and the RS3 didn't roll much either. It feels direct and definitely feels rear driven.
I have a 2024 BMW IXM60 that came with run-flat tires. While driving around 40 mph, I hit a pothole and the run-flat instantly went flat and did not at all feel safe to drive on except for a couple blocks back to my home. I would not spend the extra money for run flats, did not find any benefit at all from it.
Im 6000 miles in on my i4 m50 and the tires are about to be replaced. Its a super powerful and super heavy car and it will eat up tires like nothing.
Awesome bike, but swap out the stock tires asap.
As others mentioned, run-flats are more suspectable to sidewall damage. They're also heavier and noisier. Also, you may have a wider selection of tires if you go with non-runflat.
I got the wheel and tire warranty when I bought my car. They’ve already replaced 4 run flats for free. I got 2 blowouts in the last 2 weeks hitting pretty average sized potholes that I’ve never had issues before with. Run flats suck.
Swapped my wifes Z4 from runflats to normal.
Pros: better ride, less likely to crack rims, cheaper tyres.
Cons: no spare tyre.
Before I switched I had 4 sidewall tears, one bent wheel, and one cracked wheel. $3000 in damage. After I switched, zero issues a year and a half later. Smoother ride and less road noise too.
For better handling and winter traction, I would consider getting wider tires.
